KYAU Network
KYAU NetworkKYAU Network is powered by Arch Linux and KYAU Labs. While once utilizing dedicated servers to power, everything is now located on-site via the local KYAU Labs datacenter with external access being routed through a VPS using a Wireguard VPN. KYAU Labs chiefly utilizes Kernel-based Virtual Machines (KVM) to separate services onto separate virtual machines (VMs). Each VM and/or VPS is setup using kyaulabs/aarch. The service VMs themselves are run using Libvirt with the disk volumes sitting on LVM thin volumes on-top of RAID10(far2).
Security & Reliability
Security & ReliabilityOur network has been setup with security and reliability as our two primary focus points. Our DNS server has been setup to achieve an A+ with 100% in all four categories on DNS Spy. Our web server, running nginx with Let's Encrypt SSL certificates, has been setup to achieve an A+ rating with 100 points in every category on SSL Labs.
 | We are currently looking for a low-end, multiple IPv4, VPS provider on a separate network/continent for our slave DNS server |

Why Arch Linux?
Arch Linux was an in-house decision not taken lightly, in 2013 the switch from FreeBSD to Arch Linux was made without regret. Running Arch Linux on a server in a production environment is very feasible, provided you know a bit about security and keep on top of advisories. That being said we do not live in a perfect world, and server logs are proof of that.

Shell Box
The shell box is our on-going experiment/education in security. It is powered by OpenBSD and is open to anyone, provided they are willing to go through the application process. More details should be available soon.
 | WARNING: The Shell Box was shutdown once the network was brought in-house. |
"One of the things I have always wanted to do since I was a younger was to run a shell provider. Shy of some dabbling with Slackware, which I installed from a CDROM I got in the back of a book at the local library (pre-internet joys), this was my first major introduction to Linux and the command line. I spent a good majority of my youth on IRC messing around with "shells". I even got my first major introduction to programming (aside from BASIC and HTML) when I started coding botnet scripts for eggdrop in TCL." ~Kyau
